Great explanations sir! Thank you! Sadly, we have friends who just bought a house 2 weeks ago and they've quickly found there were sewage drainage problems and possibly other plumbing issues and permitting problems on past jobs. I really feel for them as they don't know much about those issues. An inspector can't find everything plumbing related, but when you see a concrete patch in the garage, my antenna would go up immediately with questions about what was done here/when and was it permitted. They're having a lot of work done now on a home they've been in for 2 weeks... ☹

[@lorirose7126]

Thanks! Great video. I am an interior architectural designer helping design my parents' bathroom IN A HIGH RISE CONDOMINIUM/apartment building in Florida. We are on the 3rd floor. There are 4-5 units per floor and 12 floors total. I have worked mostly in the UK and Asia and some US regulations are different based on UPC or IPC. I am NOT an expert in venting or vent stacks but I know we need them. I have read the vent stack cannot be less than 6 feet for the closet flange of the WC/toilet. We had a plumber in for a look and quotation and he suggested our toilet had a vent stack right behind it making a wall-hung toilet and hidden cistern impossible. However, on the architectural plans (not AS BUILT), there is a VS and SS just about at 6 feet from the existing WC toilet. If I am correct and there is only one vent stack and one soil stack at 6' or less, is it possible that the plumber was incorrect? I got the feeling he likes to keep life consistent without change or new plumbing ideas for convenience. But I don't want to misjudge him! We are also speculating on installing a single breaker tankless water heater and he groaned at that. Well, he groaned more at the idea of a whole home 3-breaker tankless water heater. What is your experience with ELECTRIC tankless water heaters in the USA? Nay or Yay? THANKS SO MUCH IF TIME IS POSSIBLE TO REPLY.!!

[@MrCoreyCoreyCorey]

Thanks for the video! This helped me a lot! I don't know if you'll see this, and speaking of dry vents - I bought a 55 year old bungalow and I've discovered there is what I suspect to be an old copper 2" dry vent. I was noticing some drips/green stains near the bathroom basement ceiling fan vent cover and on the floor beneath the fan. I saw that there was just a horizontal run of this 2" mystery copper pipe, left uncapped and open right next to the fan body, it was dripping down though the grate. I assumed I was getting condensation from it. Well, what do I know? Not enough! I got a fitting and capped it. Seemed okay for a time. One day much later, heard a loud bang, and big mess from the basement ceiling. So I rip out that section of ceiling, and I see this same 2" pipe had a bend to send it vertical and through a main floor bedroom wall. The soldered bend gave way and dumped what was collecting in this pipe. Today I see in the attic that this pipe goes up into some long cylindrical copper fitting (maybe 4 or 6 inch around) and out through the roof. Would you have any suggestions for decommissioning this properly? I think the only thing to do is remove the whole darned thing, it's likely to attract condensation any way I think about it, and if I cut and cap it anywhere I'll have the potential to trap water that might surprise me again with damage. Anyway, if you happen to see this and have any thoughts I'd appreciate it!

[@risingtideplumbing]

Hey there. It sounds like you have the right idea as far as getting rid of it if possible. If you just cap it, it will just fill with rain water over time. You would just need to make sure that there is nothing else tied into it before you completely abandon it. The other option would be to find a way to tie it into the existing sanitary sewer so it all is connected. Hope this helps.

[@mungojerry4713]

Thank you, very helpful. I'm thinking about taking on, as far as I'm concerned, A very big plumbing project in my newly purchased home. I have a couple questions: On the dry vent examples, can those san tee's be on their back like they are? I was told they had to be turned at a 45 degree angle? Also, how far do the vents have to be from the fixture? I suppose it depends on the pipe size? I live in San Francisco where you can not use PVC. You have to use cast iron. Do the same codes apply for both materials?

Can you do one on gray water from the shower and washer for those of us trying to grow shade in Phoenix, AZ while respecting water conservation ordinance?

[@michaelsparks6084]

Pretty solid explanations, although California Code and the International Code has a couple of extra requirements for wet venting, namely. The vent line must be taken off the drain above the cross section and you must increase the drain pipe size by 1. Example: The pipe going to the lav off of the shower would need a 22* or 45* fitting and the pipe from that wye to the 3’’ would need to be 2 1/2’’ or 3’’. The other Lav would only need a 22* or 45* since the tub drain minimum is 11/2’’ an I believe you ran 2’’. I am sure the way you have these fixtures plumbed they would work perfectly, this is just the codes we have to adhere to in my world. Also I have Plumbed in Europe and also own a couple of houses there and our standards are more rigorous to put it kindly. (Licensed Plumbing Contractor for 30 years, retired)

Nice video. My home is a 1968, with one main vent stack. I have a 1/2 bath with a washer/dryer sharing one room in the basement. Id like to relocate the washer and dryer just outside of that room, and install a shower in their place. Obviously there's some concrete busting and routing to do, but would adding the additional, new washer drain to that area pose any issues? Figure the water lines and electric are currently accessible, so hoping moving the washer/dryer a few feet wont be a total nightmare to add that much needed 2nd shower.

[@kotaplumbingandheating]

In Canada, the wc has to be the most downstream connection in the wet vent. It can be symmetrically connected however it still must be the last fixture draining onto the branch

[@chcataneo]

In Florida we call that major over minor. You cant run a major past a minor............

[@joshm5816]

Kinda a dumb way to plumb. If everything downstream of a water closet is vented, then the toilet will cause no issues. If you're talking a major over a minor, in my area, that would be in the vertical. For example, tying in a washing machine on top of a lavatory below would definitely cause issues.

[@kotaplumbingandheating]

The water closet is the most downstream on the wet vented branch due to the volume and velocity of the water moving through the pipe after a flush the concern is that it could siphon a trap if the WC upstream of say a tub or shower

[@larryzdanis5377]

Very good video.. I didn't realize you could oversize a pipe and use it as a wet-vent for other fixtures. I'll share one comment regarding the straw-analogy which is so commonly used. The straw analogy isn't terrible, but its not perfectly accurate, and here is why: There isn't typically a hand or plug over a plumbing fixture drain (unless you plug the drain.. and then there should be no question as to why its not draining), so such a "suction" isn't normaly present in plumbing system, even an unvented section. However, water within a pipe full-of-water does resist changing shape as flow and would therefore suck a P-trap dry since it resists separation (or shape change) in the absense of air to allow separation (or shape change.. ie., taking up more pipe-length and less of the pipe's full cross-section). The primary purpose of the vent is to break this vacuum downstream of the ptrap, to allow air to enter downstream of the ptrap so that the water can settle to the bottom of the pipe, thereby braking the solid-pipe-full-of-water vacuum that would potentially suck the ptrap dry.

[@Moondoggy1941]

We had a large shower install where a roman tub was, we payed to have the concrete floor busted out and moved the drain to the middle of the shower, we have always had issue after the fact, ankle deep in water, when the shower drain is working you can hear the sucking, do you think it is the venting might be clogged or poor drain install?

[@larryzdanis5377]

@@Moondoggy1941 sounds like a clogged drain.. vent problems should only slightly slow drainage if that.. vent issue can cause ptrap to be sucked dry, but that doesn't sound like your problem

[@dmills13F]

Very few of my colleagues in the U.S understand why we vent. Anti science is very strong in this trade and most plumbers will cling to the simplest analogy they can wrap their heads around to explain something in plumbing. Thumb over the straw, (try that with 1.25" pipe) stab a water bottle and it will drain better, (except we don't reduce pipe downstream which is what a bottle represents). Even when confronted with a direct practical test, I've literally demonstrated to my coworkers with capped off vents during new construction that unvented fixtures drain just fine, they still refuse to accept it. Sometimes all you can do is repeat the mantra, venting protects trap seals, and move on.
